首先需要配置密钥和密码

vim ~/.aws/config[default]output = json   #输出格式region = ap-northeast-2  #默认区域

创建密钥文件

vim ~/.aws/credentials[default]aws_access_key_id = *****aws_secret_access_key = ****

编写上传脚本

#!/usr/bin/pythonimport loggingimport boto3from botocore.exceptions import ClientErrordef upload_file(file_name, bucket, object_name=None):    """Upload a file to an S3 bucket    :param file_name: File to upload    :param bucket: Bucket to upload to    :param object_name: S3 object name. If not specified then same as file_name    :return: True if file was uploaded, else False    """    # If S3 object_name was not specified, use file_name    if object_name is None:        object_name = file_name    # Upload the file    s3_client = boto3.client('s3')    try:        response = s3_client.upload_file(file_name, bucket, object_name)    except ClientError as e:        logging.error(e)        return False    return Truedef main():    """Exercise upload_file()"""    # Set these values before running the program    bucket_name = 'test-bucket'    file_name = 'testfile'    object_name = 'testfile'    # Set up logging    logging.basicConfig(level=logging.DEBUG,                        format='%(levelname)s: %(asctime)s: %(message)s')    # Upload a file    response = upload_file(file_name, bucket_name, object_name)    if response:        logging.info('File was uploaded')if __name__ == '__main__':    main()

下载脚本

#!/usr/bin/pythonimport boto3import botocoreBUCKET_NAME = 'test-bucket' # replace with your bucket nameKEY = 'testfile' # replace with your object keys3 = boto3.resource('s3')try:    s3.Bucket(BUCKET_NAME).download_file(KEY, 'testfile')except botocore.exceptions.ClientError as e:    if e.response['Error']['Code'] == "404":        print("The object does not exist.")    else:        raise

使用aws cli上传下载

#上传aws s3 cp ./testfile s3://testbucket/   #下载aws s3 cp s3://testbucket/testfile ./
